Title: Reflection loss measuring method
Inventor: FUNAHASHI TAKAO
IPC: G01M11/02
Filed: 1982-12-29
Abstract: PURPOSE:To measure a reflection loss by a difference of peak values of both pulses by using an optical pulse generator as a light source, and separating an optical pulse which leaks at the near end of an optical directional coupler, and an optical pulse which is reflected by an optical boundary surface of an optical fiber, etc. and goes and returns. CONSTITUTION:A pulse signal outputted from a pulse generator 5 is converted to an optical pulse having the same pulse width and period as an input by an optical transmitter 7. In an optical directional coupler 2, the optical pulse signal leaks into a point C by a near-end leakage to the point C from a point A, and it is inputted to an optical receiver 6. On the other hand, the optical pulse signal which passes through a point B from the point A passes through an optical fiber 4 for a delay, is reflected by an optical boundary surface 8, passes through the optical fiber 4 again, passes through the point C from the point B, and is inputted to the optical receiver 6. As for said two pulses which are photoelectric converted and amplified, a level ratio of its peak values is read by an oscilloscope 9.

Title: Spot position error detector for optical pickup
Inventor: TSUBOI MIGAKU
IPC: G11B7/09
Filed: 1989-09-07
Abstract: PURPOSE:To reduce apparent track offset by making small the effective diameter of an area, where a beam for tracking error detection is cut off, in an optical path splitter rather than the beam diameter of a circular beam in returning light in a just focus state. CONSTITUTION:A prism is used for independent division into four components such as areas A1 and C3 for focus error detection, for which + or - first-order diffracted light components are excluded as much as possible, the areas B2 and D4 for track error detection for which one part of the + or - first-order diffracted light components is cut off by a shielding part 63. As a photodetector, a 6-divid type photodetector 26 is used. By respectively forming inclination reversely, spots are formed for correspondent photodetection parts 27 and 28. When the effective diameter of the areas B2 and D4 is made smaller than the diameter of the circular beam in the returning light, the effective diameter is reduced so that the quantity of light for the transmissive light of the areas B2 and D4 can be reduced to the 70% of a case that the effective diameter is larger than the diameter of the circular beam in the returning light. Thus, the apparent track offset amount can be reduced to be half.

Filed: 1990-09-04
Abstract: PURPOSE:To carry out the binary subtraction at high speed by performing the subtraction conversion in circuit constitution where the logical arithmetic of an exclusive OR is mainly carried out without using a special circuit structure needed for borrowing a digit when the subtraction is performed by an electronic computer. CONSTITUTION:A 4-digit subtracted register 3 which can store the result of subtraction stores a binary number 1000, and a 4-digit subtraction register 4 stores a binary number 0010 with the same position secured among those digits. Then each code of the higher rank digits starting at a digit 6 of the register 3 having the same position as a digit 5 of a code 1 of the register 4 is converted into a code of an exclusive OR secured with the code 1(7) up to a digit 8 where the code is equal to '0'. Thus the subtraction conversion is attained and a subtraction conversion code (9)0110 of the register 3 which recorded the result of the subtraction conversion is the result of subtraction. As a result, the binary subtraction is carried out at high speed.

Title: Residual quantity detector
Inventor: MASADA HIROSHI
IPC: G01F23/20
Filed: 1994-09-02
Abstract: PURPOSE: To detect the residual quantity of a material filled in a container through a simple, inexpensive and versatile constitution where the deformation of a pressure-sensitive body, corresponding to the residual quantity of material filled in the container, causes deformation of a Bourdon tube. CONSTITUTION: When a container, e.g. a kerosene tank, is mounted on a receiving table 4, a gravitational pressure F is applied to an elastic pressure-sensitive body 2 filled with an unshrinkable fluid. Consequently, the pressure-sensitive body 2 is deformed and the applied pressure F is transmitted through the fluid to a Bourdon tube 3 which is thereby deformed. The Bourdon tube 3 is deformed depending on the weight of mounted container, and thereby the weight of the material filled therein, and the Bourdon tube is deformed (bent) gradually from a straight state as the residual quantity of the material decreases.  When the detector is constructed such that the forward end position of the bent Bourdon tube 3 can be recognized visually through a window 1a in the housing 1, when the residual quantity of material in the container decreases below a predetermined value, decrease of residual quantity of material in the container can be detected.

Abstract: PROBLEM TO BE SOLVED: To maintain the degree of vacuum of the vacuum heat insulating layer of a heat collecting tube for a solar heat collecting device in a high degree. SOLUTION: A gap, formed between the outer tube 1a and the inner tube 1b of a solar heat collecting device, is evacuated to form a vacuum heat insulating layer 1c.

Accordingly, the operating frequency of the vacuum pump 9 is reduced and the increase of operating cost or the deterioration of life of the pump 9 can be prevented.

Title: Method and apparatus for measuring distribution of crystal grain orientation in directional silicon steel plate
Inventor: ICHIKAWA FUMIHIKO
IPC: G01N33/20
Filed: 1988-09-20
Abstract: PURPOSE:To make it possible to perform measurement efficiently online without contact and without destruction, by inputting burst-shaped ultrasonic wave pulses including two or ore waves having frequencies which are approximately integer times or half-integer times of twice the thickness of a steel plate in the direction of the thickness of the plate. CONSTITUTION:A timing control circuit 22 outputs repeating pulses in response to the scanning speed of a probe. In synchronization with the pulses, a pulsor 20 generates an electric signal of a burst waves of about 10 waves of frequencies f=v/2d ((v) is sound speed and (d) is plate thickness). An ultrasonic wave probe 12 transduces the electric signal into, the ultrasonic wave signal and inputs the signal into a test specimen 11. A reflecting plate is arranged beneath the specimen 11. The ultrasonic waves transmitted through the test specimen 11 are reflected from the reflecting plate and inputted into the probe 12 again. The ultrasonic waves are transduced into the electric signal. The electric signal is amplified in a receiver 28 and outputted to a gate circuit 30. The gate circuit 30 is opened with a specified delay in synchronization with the pulses from the circuit 22. Thus, only the interference multiple- reflected-wave signals are made to pass through a peak/hold circuit 32. The abnormal grains and the normal grains can be judged from the magnitudes of the signals.
